英文摘要	Inexpensive and eco-friendly luminescent Cu(i) complexes are ideal.phosphorescent emitters for high efficiency organic light-emitting diodes (OLEDs). A series of pyrazinyl carbazole (CPz) compounds were designed and synthesized to obtain efficient luminescent Cu(i) complexes through reaction with Cul using a vacuum codeposition method. Based on photophysical studies of the CPz compounds and their codeposited Cul-CPz films, the compound 9-(3-(6-(carbazol-9-yl)pyrazin-2-yl)phenyl)-carbazole (CPzPC) with Cul was chosen as the emissive layer for OLED fabrication, where the emitter was identified as Cu-2(mu-I)(2)(CPzPC)(4) on the basis of X-ray absorption spectroscopy. After optimizing the device architecture and material selection including the Cul doping concentration and hole transporting Layer, an efficient orange-red emitting OLED with a maximum emission band, an external quantum efficiency (EQE), and a luminance of 590 nm, 6.6% and 8619 cd m(-2) (10 V), respectively, was achieved.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000340353700012&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Materials Science, Multidisciplinary; Physics, Applied; SCI(E); 9; ARTICLE; wangjianqiang@sinap.ac.cn; zwliu@pku.edu.cn; 31; 6333-6341; 2
